FREEZE-THAW STABLE POLYACRYLAMIDE EMULSIONS |
摘要 |
Water-in-oil emulsions of water-soluble polymers, i.e. polyacrylamides, which are subject to freeze-thaw degradation are stabilized against repeated freeze-thaw cycles by incorporating specific ethoxylated alkylphenol surfactants containing low levels of ethoxylation. Moreover, the resultant emulsions exhibit superior resistance to sheet gel formation under ambient storage conditions. |
